Periodic Table Groups Vs Periods
A group is a vertical column in the periodic table of elements.
Periodic table groups vs periods. Both describe elements that share common properties, usually based on the number of valence electrons. Groups and periods are two ways of categorizing elements in the periodic table. Groups the different rows of elements are called periods.
Modern period has eighteen groups from 1 to 18, seven periods (rows) and two sub periods. The elements in a group have similar physical or chemical characteristics of the outermost electron shells of their atoms (i.e., the same core charge), because. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements.
For the most part, element families and element groups are the same things. The periods on most periodic tables are label on the left side of the periodic table by number 1 through 7. Hence, this is the key difference between periods and groups of the periodic table.
Modern periodic table has 18 columns called groups and 7 rows called periods. Groups are the elements having the same outer electron arrangement.the outer electrons are also called the valence electrons. Modern periodic table has no concept as such.
In the periodic table, the vertical columns are called ‘groups’ and the horizontal rows are called ‘periods’. In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.there are 18 numbered groups in the periodic table; May 9, 2018 sushil humagain uncategorized 0.
